Returns the natural (base-e) logarithm of the complex number
x using the principal branch, whose cuts are along the negative real axis.
The value computed is bounded along the imaginary axis between
[-i*PI,i*PI].
When
x is a negative real number,
log(x).imag() is PI.
This overloads
cmath's log function.
Parameters
- x
- Complex value.
Return value
Natural logarithm of
x.
